This school holds a secret: if you are lucky, you will find here the best friend in the world. A magical animal. An animal that can talk. If it belongs to you.

Eddie gets the funny bat, Eugenia, and all of the class envies him. Almost all of them. One girl does not want to have a magical animal. Will the teacher Miss Cornfield agree? The big read night is pending. However, for some children, the evening takes a dangerous turn: they find themselves in the creepy "Keller of the Grauens" again - trapped deep below the school. Can the magic animals help them?
